From Wikipedia:

Lessons of Darkness (German: Lektionen in Finsternis) is a 1992 film by director Werner Herzog. Shot in documentary style on 16-millimetre film from the perspective of an almost alien observer, the film is an exploration of the ravaged oil fields of post-Gulf War Kuwait, decontextualised and characterised in such a way as to emphasise the terrain's cataclysmic strangeness. An effective companion to his earlier film Fata Morgana, Herzog again perceives the desert as a landscape with its own voice. A co-production with Paul Berriff, the film was financed by the television studios Canal+ and Première.
